The main purmose of this study is to establish the corelatione between the ink receptivity and the surface 초\ulcorner岺\ulcornerparamenters in the presence of the dampening solution in the Lithographic Printing. The surface chemical parametere are calculated from the components (dispersion part and polar part) of which the surface tension of various surfaces acd ink are estimated from the contact angle The conclusions are; 1) the receptivity of ink depends on the value of polar part of surface tension, ; and ink, ;and decreases as the value of and increase, 2) the adherence of ink depends on the value of ink and dampening solution, and decreases as the value of dampening solution, decreases on the image area.
